Dear Mr. Wynn,
Thank you for posting your question on History Hub!
Also, we would also suggest looking into the finding aids for records located in the Records of the Office of Strategic Services (OSS) (Record Group 226) available online at: https://www.archives.gov/iwg/declassified-records/rg-226-oss. A full list of series located in RG 226 may be found at: https://www.archives.gov/research/military/ww2/oss/series.html.
Please contact the reference unit(s) listed in the records descriptions or NARA website for access to the non-digitized records. Please note that due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from various NARA units. We apologize for this inconvenience and appreciate your understanding and patience.
Further, we searched CREST (Central Intelligence Agency (CIA) Records Search Tool) at https://www.foia.cia.gov/search/ for “Rommel Erwin.” The search results may be viewed here. Information concerning CREST is provided on the CIA web site at https://www.foia.cia.gov/collection/crest-25-year-program-archive.
In addition, we suggest reviewing some published works on Erwin Rommel such as “Field Marshal: The Life and Death of Erwin Rommel” by Daniel Allen Butler to see if such a plan was mentioned.
We hope this is helpful. Best of luck with your research!
